Question

HELP!!!! PLEASE! 10 POINTS Which function is graphed?

Answer 1

`x`Answer:

The answer would be
`f(x)=2x-6`

Explanation:

The question is basically asking for the slope intercept form and
`f(x)` is equal to
`y`. So after we have figured that out we would have to know what the slope intercept form is, slope intercept form is simply
`y=mx+b`. In the equation
`m` will equal the slope or the rise over run and
`b` will equal the y-intercept and that is all we need to solve this equation.

If we look at the graph we will see that the line crosses the y axis at the point (0,-6) so knowing that we will remember that
`b` is the y-intercept is where the line crosses the y axis and in this case it is crossing it at -6 so if we plug that into the equation we will get
`y=mx-6`.

Now we will find the slope or
`m`. First we will see the distance between the 2 points on the graph, if we count we will have to go up 6 to get to (0,0) and we will go right 3 so we know that slope is rise over run so you would go up or rise 6 and go right or run 3 so we would get
`(6)/(3)` as our slope, but we could simplify this to just 2 so we would get
`2x` as our
`mx`.

We have solved all of the parts and now we can put it together. So first we would do f of x or
`f(x)` which means function and than we would put
`2x` and finally we would put our
`-6`. When we put that all together we would get
`f(x)=2x-6`.

To check you could just graph this and you would get:

P.S. The f(x) turned into a y in the process:)

Answer 2

f(x)=2x-6

Explanation:

Because the slope is 2 and the y-intercept is -6.
